Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel processing, in particular to a sand and gravel separator with adjustable screening aperture. Background Art

[0002] Sand and gravel is a commonly used building material, widely used in construction, roads, bridges, water conservancy and other projects. It is a granular material made from natural ore through crushing, screening and other processes.

[0003] The main components of gravel are quartz and feldspar. Quartz is a kind of ore with high hardness and good wear resistance, and has good physical and chemical properties, which can ensure the durability and stability of gravel. Feldspar is a kind of ore containing elements such as sodium and potassium, which has good fire resistance and compression resistance. These components make gravel have good physical and mechanical properties and can withstand large loads and pressures.

[0004] After grinding, the sand and gravel raw materials need to be screened and separated. The particle sizes of sand and gravel raw materials with different requirements after grinding are different. Therefore, if the particles of the sand and gravel raw materials are small after grinding, the filtration effect will be poor and the size of the filter pore size cannot be adjusted. Therefore, further improvement is needed. Utility Model Content

[0006] The adjustment support mechanism comprises: a hanging frame, a sliding push frame, a connecting frame, an arc guide plate, a driving part and a limiting part;

[0007] The hanging frame is arranged on the upper end surface of the base frame, the sliding push frame is arranged at the bottom of the drainage and filtering slide, the sliding push frame and the drainage and filtering slide are spliced ​​through a limiting portion, the connecting frame is arranged on the lower end surface of the sliding push frame, the arc-shaped guide plate is connected to the connecting frame, and the driving part is arranged on the base frame.

[0008] Preferably, the driving part comprises: a cylinder fixing frame, a pushing cylinder and a driving frame;

[0009] The cylinder fixing frame is arranged on the base frame, the pushing cylinder is embedded in the base frame, the driving frame is arranged at the telescopic end of the pushing cylinder, and the upper end of the driving frame is connected to the sliding pushing frame.

[0010] Preferably, the limiting part comprises: a limiting track and a limiting strip;

[0011] The limiting track and the limiting strip are respectively arranged between the sliding push frame and the drainage and filtering slideway, and the limiting strip is embedded in the limiting track.

[0012] Preferably, the drainage and filtering slideway and the bottom of the sliding push frame are both provided with filtering mesh holes.

[0013] Preferably, the hanging frame is an inverted J-shaped structure, and the hanging frame is connected to the top of the drainage and filtering slideway.

[0014] Preferably, a supporting vertical plate is provided on the lower end surface of the base frame.

[0015] Beneficial Effects

[0016] The utility model provides a sand and gravel separator with adjustable screening aperture, which has the following beneficial effects: the size of the filtering aperture can be adjusted during the filtering process after the sand and gravel raw materials are ground, so as to meet the filtering needs of sand and gravel with different particle sizes.

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] Example: See Figure 1-3In order to adjust the size of the filter aperture during the filtering process of the sand and gravel raw materials after grinding, so as to meet the filtering of sand and gravel with different particle sizes, the specific working principle is as follows: the ground sand and gravel are poured into one end of the drainage filter slide 2. Since the drainage filter slide 2 supported by the support vertical plate 13 is in an inclined state, the flow filtering of the sand and gravel is carried out, and the driving frame 9 is driven by the pushing cylinder 8 in the driving fixed frame to move, so that the sliding push frame 4 is moved. When the sliding push frame 4 moves, the filter mesh 12 between the sliding push frame 4 and the drainage filter slide 2 changes, so that the filter mesh 12 has an overlapping area, so that a part of the filter mesh 12 is blocked, thereby realizing the change of the mesh diameter during the filtering process.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
